But it was then threeish or fourish, much too late to return to the salt mines. So I drove home, slowly and cautiously, and took a nap.

I roused an hour later, full of p v, and went for my daily swim. The Atlantic is just across Ocean Boulevard from the McNally digs, and I try to do two miles each day, chugging along parallel to the shore and hoping no Portuguese man-of-war is lurking nearby, licking its chops. I returned home in time to dress and attend the cocktail hour, a family ceremony. That evening, as usual, my father did the honors, stirring up a pitcher of traditional dry martinis.

My mother, Madelaine, is one of the ditsiest of all mommies, but a lovely gentlewoman who talks to her begonias.

She also drinks sauterne with meat and fish courses and is very concerned about the ozone layer, without quite knowing what ozone is.

My father, Prescott McNally, has been playing the part of landed gentry so long that he has become exactly that: a squire, rectitudinous attorney, and possibly the most hidebound man I know. He has a wide Guardsman's mustache, tangled as the Amazon rain forest, and I like to visualize him wearing a busby, planted outside Buckingham Palace, staring fixedly into space.

I don't wish to imply that my parents are "characters." They, and I, would be offended by that designation. They are just very decent, loving, and lovable human beings. They have their oddities-but who does not? I happen to believe I do a marvelous imitation of Humphrey Bogart, though friends assure me I sound more like Donald Duck.

What I'm trying to convey is that I love my parents. Of course. But just as important, I enjoy them. How many sons and daughters can say that?

That evening I was wearing the palest of pink linen suits with a deep lavender polo shirt of Sea Island cotton. Tasseled white loafers with no socks, of course. My father raised one eyebrow (a trick I've never been able to master), and I hastened to explain the glad rags.

"I'm attending an exhibit at the Pristine Gallery tonight," I said. "Silas Hawkin's paintings. I understand the showpiece will be his latest work, a portrait of Theodosia Johnson."

"Ah," the guv said.

Mother looked up. "I've met her father," she declared. "Hector Johnson. A very fine gentleman."

The pater and I exchanged glances.

"How did you happen to meet him, Maddie?" he asked.

"Why, he joined our garden club," she said. "He's only been in South Florida a short while-about a year I think he said-and he's into orchids. He seems very knowledgeable."

"How old is he, mother?" I inquired.

"Oh, I don't know, Archy," she answered. "Mid-sixties perhaps. Shall I ask him?"

McNally pere smiled. "I don't think that will be necessary," he said. "A civilized man?"

"Charming," mother said, "just charming! He said my 'Iron Cross' was the healthiest begonia he had ever seen."

Father gulped the remainder of his martini. "That was very kind of him," he said, absolutely deadpan. "Shall we go down to dinner?"

I remember well the menu that night, the way I imagine the condemned might savor their last meal before the unknown. Ursi Olson, our cook-housekeeper, had sauteed red snapper with white wine and shallots. And husband Jamie, our houseman, served the dessert: chocolate torte with cappuccino ice cream. Any wonder why the waistbands of my slacks continue to shrink?

Before departing for the Pristine Gallery I climbed to the third floor of the McNally faux Tudor manor. There, under a leaking copper roof, I had my own aerie, a rather dilapidated but snug suite: sitting room, bedroom, bath. Not luxurious, you understand, but you couldn't beat the rent. Zip.

Since becoming chief of Discreet Inquiries at McNally Son, I had kept a private journal in which I recorded the details of my investigations. It was an invaluable aid in keeping track of things, especially when I had two or more cases running concurrently. I jotted down facts, impressions, bits of actual dialogue, and whatever else I thought might be of value. Most of my scribblings turned out to be of no value whatsoever. But one never knows, do one?

That night I hurriedly made brief notes on my interview with Mrs. Gertrude Smythe-Hersforth, the chat with Simon Pettibone, the information learned at that bibulous luncheon with Lolly Spindrift, and what mother had mentioned about Hector, Theodosia Johnson's father. Finished, I read over what I had written and found absolutely zilch in the way of inspiration. So I closed up shop, clattered downstairs, and went to meet my fate.

It was a still, cloudless night but hot and humid as a sauna. As I drove back to Worth Avenue I hoped the owner of the Pristine Gallery, Ivan Duvalnik, would have the decency to serve something refreshing. He did: a Chilean chardonnay so cold it made my fillings ache.

It turned out to be a hugger-mugger evening, the gallery overcrowded, chatter too loud, paintings almost hidden by the billows of chiffon gown (f.) and the sheen of silk sport jackets (m.). I knew most of the guests and mingled determinedly, working my way toward the piece de resistance: the portrait of Theodosia Johnson.

When I finally stood before it, I was simultaneously rapt and unwrapped. I mean I was totally engrossed and at the same time felt a sag of the knees and a horrible need to let my jaw droop and just gawk. Spindrift had not exaggerated; the lady was a corker. What beauty! But not of the plastic variety one sees so often in fashion ads and centerfolds. Again, Lolly had it right: she was half-Garbo, half-Dietrich, with all the mystery and promise in those two mesmerizing faces.

I am not an expert on paintings, figuring one man's "September Morn" is another man's "Les Demoiselles d'Avignon." But I defy any hot-blodded yute to look at that portrait of Madam X without saying to himself, "I must meet her."

I was filling my eyes when a voice at my elbow interrupted my fantasies by stating, "Awfully good, am I right, Archy? Si has caught her expression perfectly, and the colors are striking. Don't you agree?"

I turned, and there was the Chinless Wonder himself, Chauncey Wilson Smythe-Hersforth, wearing a midnight blue dinner jacket and looking like the groom on a wedding cake. His pushbroom mustache was meticulously trimmed and he was exuding a fruity cologne. That was a surprise. CW was known as a nebbishy sort of chap. Palm Beach gossips (the total population) claimed he wore a helmet while pedaling his Exercycle.

"You couldn't be righter, CW," I said. "Or more right- whichever comes first. Hawkin has done a marvelous job, and the lady is beautiful."

"My fiancee," he said with a fatuous grin. "Or soon to be."

"Congratulations!" I said, smiling, and recalling that "one may smile and smile, and be a villain."

"Well, it's not exactly official yet," he said in that pontifical way he had of speaking. "But it soon will be, I assure you."

"I'd like to meet the lucky lady," I said, perking his ego. "Is she here this evening?"

"Somewhere," he said vaguely, looking about the mobbed gallery. "Just find the biggest crowd, and she's sure to be the center."

Then he drifted away, obviously having no desire to introduce me personally. Quite understandable.

I glanced around and saw in one corner a jammed circle of men surrounding someone I presumed to be the star of the evening. Rather than join the adoring throng, I eased my way to the bar to replenish my supply of that excellent chardonnay. And there I bumped into Silas Hawkin, the famous portraitist and plastic surgeon himself.

"Hi, Si," I said, thinking how silly that sounded.

He stared. "Do I know you?" he demanded.

We had met several times; he knew very well who I was. But feigning ignorance was his particular brand of one-upmanship.

"Archy McNally," I said, as equably as I could.
